Electron Microscope

Key facilities

Transmission Electron Microscope (TEM)

The Philips CM10 TEM had
a digital camera installed in April 2017. It is used to image very
small objects such as bacteria and viruses. The TEM is
incredibly helpful in looking at nanoparticles and locating
antibodies to label parts of cells.

Scanning Electron Microscope (SEM)

Installed in March 2017, the FEI Quanta FEG 650 is a field
emission SEM with a resolution of 1.2 nanometres. It can be
used to image nanoparticles at magnifications of x 300,000. It can
also be used to look at larger wet samples.

X-ray Microanalysis (EDX) available on the SEM

The Oxford Instruments Aztec EDX system (installed in April
2017) is used to identify elements (eg iron, oxygen and carbon)
that compose a sample. It is able to construct maps
showing the location of the elements.
